rename the types with spaces in them to use - (#9929)

# Description
before this PR,
```nushell
> $.a.b | describe
cell path
```
which feels inconsistent with the `cell-path` type annotation, like in
```nushell
> def foo [x: cell-path] { $x | describe }; foo $.a.b
cell path
```

this PR changes the name of the "cell path" type from `cell path` to
`cell-path`

# User-Facing Changes
`cell path` is now `cell-path` in the output of `describe`.
this might be a breaking change in some scripts.

same goes with
- `list stream` -> `list-stream`
- `match pattern` -> `match-pattern`

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`
- ⚫ `toolkit test stdlib`

this PR adds a new `cell_path_type` test to make sure it stays equal to
`cell-path` in the future.
